Optical Dove Prisms

A Optical Dove prism is a truncated version of a right-angle prism, used as a
reflective prism inverting the image. It will create an image that is twice the
angle of your rotation.
Dove prisms are a type of optical prism that offers a unique geometric
configuration that can invert images by 180 degrees. These prisms are made
using optical glass and feature a special shape that includes a 90-degree roof
angle. This provides the Dove prism with its unique properties where it can
invert images and rotate them by 180 degrees.
In addition to its unique image inversion properties, Dove prisms also offer
the ability to reflect light internally. This is due to the prism's roof angle,
which allows the light to be reflected back onto itself. This internal
reflection results in minimal light loss and high image quality.
